I don’t think greed is the main reason, they fall for these scams mostly because of stupidity.
Greed is one thing, but if you're smart, you’d still know how to manage the risk. But plain stupidity? That leads straight to regret.
I think Crwth is right, greed is one of the main reasons people fall for ponzi schemes. As we know, ponzi comes in form of high yield investment opportunities. Because greed is some person's weakness, the allure of quick and easy money can cloud their judgement, making it difficult for them not to recognize the warning signs and stay away from such investment. They invest their hard earned money and suffer huge financial loses.
The greed factor that makes people very easy to become victims, in addition to the lack of information and laziness to read. Most victims of Ponzi schemes usually follow from friend to friend without doing any research first. This scheme will continue to exist, and there will continue to be victims, this has become part of crypto.
So indeed to avoid becoming a victim, we should not be easily influenced by the lure of unreasonable profits from unclear investments, especially with profits beyond reason, it is definitely a scam. Check and recheck and use the principle of caution in investing. Keep in mind that getting rich is not easy, if it were easy, everyone in the world would be rich immediately and no one would want to work anymore.
And one more thing, the goal of investing is not to make investors rich quickly. Investment must be accompanied by patience and strong commitment and remain calm when the market fluctuates and be ready to face risks.
